I dont know but its possible, I think you should leave a little more space. Am i seeing that correctly you have a 30 gb boot drive ?
Yeah, I was so excited about it actually booting up (this is my first build) that I started downloading all of the drivers and stuff from my thumb drive onto the C drive before I realized what I was doing. Now theres only 4gb left. I think I might have to do a clean install of Windows and start fresh. I also ordered a 16gb Ballistix stick to put in for a total of 20gb. I hope those two things fix the issue. I should say that it only happens when playing Fallout 4 and Deus Ex: Mankind Divided.
